Stab connector for enclosed electric bus apparatus

Abstract

A stab type isolating connector for offset joints in enclosed high voltage electric bus apparatus comprises a removable contact rod for connecting laterally offset terminal ends of linear bus conductors within an enclosing sheath. The contact rod is slidable through a transverse passage in one terminal end into and out of engagement with a contact socket in the other terminal end, making contact with both terminal ends in its fully engaged position. Preferably the contact rod is tubular and slides over a guide rod secured within the contact socket. The guide rod may be sectional so that after seating of the contact rod a section of the guide rod may be used to secure the contact rod in engaging position.

What we claim as new and desire to secure by letters patent of the United States is: 
     
       1. Enclosed electric bus apparatus comprising: a linear bus conductor having a substantially spherical terminal end provided with a through passage transverse to the axis of said linear bus conductor, fixed contact means within said passage, a second bus conductor laterally spaced from said linear bus conductor and having a contact socket in spaced apart axial alignment with one end of said transverse passage, an enclosing sheath for said bus conductors having an opening in spaced apart axial alignment with the other end of said transverse passage, a removable closure member for said sheath opening, a movable contact rod having two contact making terminal ends, one engageable with said contact socket and the other engageable with said contact means and terminating within said transverse passage when said one terminal end is in contact-making engagement with said contact socket, said rod being axially movable through said transverse passage and sheath opening to make and break electrical connection between said bus conductors, and a removable closure cap for said other end of said transverse passage forming a portion of said spherical terminal end of said linear bus conductor while said contact rod has one terminal end in contact-making engagement with said contact socket. 
     
     
       2. Apparatus according to claim 1 wherein said second bus conductor is linear and said conductors are disposed in parallel planes with terminal ends in axial alignment with said contact rod. 
     
     
       3. Apparatus according to claim 1 wherein said contact rod is tubular and which includes, a stud coaxially and slidably positioned within said contact rod and having one end secured within said contact socket, said stud terminating within said transverse passage, and clamping means engaging said stud within said passage for securing said rod in contact making position in said socket. 
     
     
       4. Apparatus according to claim 1 which includes means within said transverse passage for securing said other terminal end of said contact rod to said linear bus conductor when said rod is in contact rod is in contact making position. 
     
     
       5. Apparatus according to claim 1 wherein said contact rod is tubular, a guide rod is provided extending through said tubular contact rod axially therof, and said contact socket includes means for securing therein one end of said guide rod, said guide rod when secured extending through said transverse passage whereby said tubular contact rod may be slidably moved coaxially over said guide rod into and out of contact making position.
